[Isaiah 9] 6-7 The Gift-Child in this passage is certainly to be understood as the same person as the Immanuel who appeared earlier. The Child is certainly none other than the virgin's son. Contrasted with the Syrian-Ephraimitic coalition, this Child brings deliverance to the people of God. Again, using the prophetic perfect, the prophet speaks of Him as though He were already born! Even the text of the Targum supports a messianic interpretation of this passage. The concept of a Messiah who is both the Son of David and the Son of God is also stated in Psalm 2:7. Notice also the play-on-words between child is born (Heb yalad, to be delivered, as in birth) and a son is given (Heb natan). Some have suggested that there is a distinction between the human birth of the Child and the divine gift of the Son. While the usage of the verbs is not conclusive, it is interesting to note that the same idea appears in Isaiah 42:1 where God gives His Spirit to His Servant. The real significance of this unique Child comes in His foretold name. Wonderful, Counselor (pele' yo'ets) is actually one title in the Hebrew (based upon the Masoretic accentuation). "Wonder," from pele', is indicative of that which is miraculously accomplished by God Himself (see Harris, Theological Word Book of the Old Testament, II, p. 723). The two words of this title are actually an appositional genitive and may be rendered "a wonder of a counselor," or "a wonderful counselor." The term "counselor" is often used in parallel with king (e.g., Mic 4:9), so that the emphasis here implies that of God-like counsel of a God-like King. The mighty God (Heb 'el gibbor), This is the strongest of titles in reference to deity. In the book of Isaiah 'el is always used of God and never used of man (e.g., 10:21). Gibbor means "hero." Whether it is used as an appositional genitive or adjectivally, in either case it is an epithet that indicates deity. There is, therefore, every indication that the Child is The mighty God Himself. Obviously, such a revelation explains how the Child in 7:14 could be born miraculously of a virgin and how He could symbolically be Immaneul (God with Us). The everlasting Father (Heb 'abiy 'ad) is a peculiar expression literally meaning Father of Eternity. He is the Lord of eternity, as well as the author of eternal life. He is, "of old, from everlasting," (Mic 5:2). Here we clearly see how the throne of David, which is to be forever, is to be preserved. It will seat a ruler Himself who is Eternal! The Prince of Peace (Heb shar-shalom). Rather than a warring monarch, He who is the Mighty God will be a benevolent Father, bringing a peace that will be eternally established in His kingdom. His reign shall be characterized by a reign of peace on earth because He is the very embodiment of peace itself. Thus, the obscure figure of Immanuel in 7:14 is now brought to clear light. We know of His kingdom, throne, world rule, peaceful reign, and eternal kingdom, as well as His virgin birth. More than this, we know who He is-God Himself incarnate!
